Have you noticed a storm of super cheap rental offers in your city's nice neighbourhoods. In Prague it is ~45% down for a week and in Sofia ~35%. My guess is Airbnb and mortgage-to-rent. With many borders expected to stay closed for an extended period, when are those properties going to end up in bank auctions?
Is the housing bubble about to pop?
If we have recession and travel restrictions for a few quarters prices will fall but still, it is just temporary.
You can expect bubble to pop only if there is some change. For example Work From Home becomes a standard and in results there is systematic outflow from urban centers. Or there is long period of inflation and the capital finds better returns elsewhere. Or 25% of population dies.
So I would say there is a chance of housing bubble popping up but it is not a base scenario.
